Why Does My Deco Keep Disconnecting – Proper Way To Fix

You may see many issues with TP Link’s Deco routers in some technological forums. Some people have been experiencing a problem where their Deco router keeps disconnecting from the internet, and they don’t know why. This issue has been going on for a while but seems to worsen. Here’s what you need to know about the problem and how to fix it.

If your TP-Link Deco keeps disconnecting, there could be a few reasons. For example, maybe the router is too far from the Deco unit, or there are too many walls between them. Another possibility is that other devices in your home interfere with the Deco’s signal. Or, it could be that the firmware on your Deco needs to be updated.

Why Does My Deco Keep Disconnecting & Tips To Solve?

If you’re experiencing constant dropouts with your TP-Link Deco mesh Wi-Fi system, it’s likely due to a compatibility issue between the Deco and your modem. On the other hand, there are some possible causes of this error listed below: 

• Cable connection issue
• Useless AC power adapter
• Not setting up the network
• Problem with firmware updates

You can do a few things to try and fix the problem. Here are my suggestions:

1. Examine the cable connection: 

Verify the cable connection if you have troubles. The connection problem happens when the cable is disconnected. Check the network cable. The connection issue develops because the wire is sometimes loosely linked to the mesh system. Securely connect the wire to the mesh.

Check for cable damage. Disconnect the cord if it’s no longer needed. This cable must be replaced. Plug this cable into a mesh system port. Turn on the electricity and check the connections.

2. Verify the mesh system’s network settings

Connection fails when network settings aren’t established. Check network settings. Open a web interface on a stable network-connected device to test network settings. The web interface requires a default login IP.

The login page is accessed by using the login ID. In mesh system settings, select network. Validate network settings. You must enable their 5GHz network if it’s off. Then, save the configuration.

3. Examine the AC power adapter

To fix the issue, check the AC adapter. The AC adaptor fails when its cord breaks. To fix manually:

1. Examine the power adapter.
2. Unplug the range extender if the adaptor fails.
3. Use a fresh AC adaptor and plug it in.

Once connected, you’ll have uninterrupted network access.

4. Launch the deco mesh system again

You must correctly validate the connection before restarting the device. Then follow these steps: 

• If the cable is connected to an access port, it must be unplugged.
• After that, you must check the LED light status.
• Then, inspect the power button and push it smoothly for 3 seconds.
• The mesh system was then turned off.
• After 10 minutes, you must restart this machine.
